Red Roof Buckhead on Druid Hills Road. This is in the northeast part of the city, and Cheshire Bridge Road (Heretic, Tokyo, Southern Nights) is close by. Dualing cum dumps are the norm. Lots of traffic. Leave your door ajar and people will walk in assuming you'll be face down ass up. Caution to cruisers - the GM is a prick and calls the police regularly. Don't sit in your car with a pipe in one hand and your dick in the other, then act surprised when you get arrested. Connect of Sniffies before you pull up so you at least know a room number you're going to.
Pig Pen is also the name of the play space inside of Flex Spa downtown. feat. sling, hanging bed, St Andrews, glory holes, and some other fuck furniture.

Happy Hunting!
